Definitions
- the present invention relates to a method for controlling stationary Extinguishing systems, in particular for the control of extinguishing systems which are equipped with liquid or gaseous extinguishing agents.
- Extinguishing devices have an extinguishing agent reservoir with liquid or gaseous Extinguishing media, which with a more or less branched piping system with the Monitoring area (building, warehouse, etc.) of the extinguishing system is connected.
- Extinguishing agents are released in the event of a fire using extinguishing nozzles, the type of which is specially designed for the delete task is aligned.
- One or more detectors are housed in fire detectors, which are often over Signal lines (detection lines) are connected to a fire alarm control panel.
- Fire alarm systems are usually made up of a large number of robust fire alarms.
- the detectors react to the creation or change of measurable Fire parameters such as temperature, radiation, aerosols or a fire characterizing Gases.
- the incoming measurement signals from the fire detectors are extracted from the Monitoring area of the extinguishing system processed and in the event of an alarm corresponding Control commands transmitted to the extinguishing device.
- fire parameters should essentially all be caused by a fire caused physical and detectable by sensor elements or detectors or chemical changes of state parameters in the monitoring area of a Fire alarm device can be summarized.
- Fire parameters are, for example, such condition parameters such as, ambient temperature, gas composition (smoldering or combustion gases), the density of optically detectable smoke or soot particles (aerosols) and of fires outgoing electromagnetic radiation in different wavelengths.
- Stationary extinguishing systems are used in many areas of fire protection of buildings, Systems or in the area of warehousing of goods for automatic fire fighting successfully used.
- the extinguishing process is triggered and the extinguishing agent is released through automatic fire alarm systems.
- the fire detectors In order to be able to detect a fire early, the fire detectors should on the one hand as close as possible to a possible place of origin of fires be arranged, but on the other hand the local conditions are too consider.
- False alarms are often caused by uncritical or processing-related sources of Smoke aerosols or gases triggered. Not even a fire temperature increase in the area surrounding a heat detector can lead to cause a false alarm.
- Extinguishing agent supplies CO 2 gas
- CO 2 gas which are used up and limited in certain extinguishing systems, then have to be replaced in a costly and time-consuming manner, the unnecessarily supplied extinguishing agents can cause damage to people and facilities or paralyze entire production areas.
- Fighting fire indoors and outdoors, especially in the home Houses and buildings with an extinguishing system and a fire alarm system comprises one or more fire detectors with at least one detector, the Detectors detect the same or different fire parameters and if exceeded one or more presettable alarm thresholds of the detected fire parameters Trigger an alarm message that activates the extinguishing device.
- DE 41 42 419 A1 describes a method and a device for detecting fire in a monitored room with the possibility of increasing the sensitivity of the detector system increase, known, with no specific number of detectors with respect to their Sensitivity is switched and the number of detectors to be switched further course of the fire is adjusted.
- DE 2344908 C2 describes a method for automatically reporting and extinguishing fires known in which the fire extinguishing device is only activated and operated after there is a flame signal, two smoke signals or one heat signal must have preceded.
- the flames should persist at certain intervals by one Flame detectors are checked and the fire extinguishing agent either maintained or shut down.
- DE19952327 A1 also describes a fire sensor and a method for detecting a Feuers discloses, in which the smoke signal emitted by the fire sensor additionally by the correlating current outside temperature and the rate of temperature rise is corrected.
- This procedure is intended to reduce the likelihood of a false alarm and at the same time an early alarm triggering can be reached.
- the fire alarm systems that have become known so far have in particular the Disadvantage that the caused by a fire and the extinguishing process physical and chemical changes in the environment of the fire detectors, such as strong smoke development, soot particles, temperature changes due to the influence of fire water or water mist, as well as in the gas composition, etc., are not taken into account. Without considering these changes in the fire area, conventional Fire alarm systems do not provide a sufficiently precise picture of the current fire situation deliver and are only suitable to a limited extent for controlling the deletion process.
- the object of the present invention is therefore a method for controlling to develop stationary extinguishing systems, to specify their operation, which the eliminates the aforementioned disadvantages.
- the process should make it possible, despite changing in the event of a fire Ambient conditions of the fire detectors are easy to evaluate and to control the Extinguishing device to generate suitable measurement signals and for effective control of the Use deletion.
- the extinguishing method according to the invention is characterized in that the detectors the fire detector after the first reliable detection of a fire by exceeding it one or more preset alarm thresholds to an increased sensitivity level be converted. This makes it possible to monitor the course of the fire despite smoke or also vapor formation through evaporating extinguishing agent as well as other disturbing influences continue to detect effectively.
- the method can be used particularly advantageously using infrared detectors use sensitive flame detectors in the fire detectors.
- the heat radiation occurring during fires can be increased by the increase according to the invention the sensitivity of an infrared detector, even when caused by the fire Reduction in the permeability of its ambient air can still be reliably detected. Furthermore, a local selection following the progress of the fire is provided the detectors to be converted to a higher sensitivity.
- the control is based on the time behavior of the fire parameters.
- An advantageous development of the method according to the invention consists in the Possibility to increase the switching processes (signal evaluation of the detectors) the sensitivity of the detectors at a selectable time interval after the Stop detection of the start of the fire.
- the individual switching processes of the detectors to a higher sensitivity level are carried out by a control unit arranged in the fire detectors or by the Fire alarm panel made.
- the measurement data of the current local data transmitted by the detectors Fire development used.
- a gradual increase in sensitivity is also within the scope of the invention like a stepless continuous increase.
- the local or spatial selection of those to be switched to increased sensitivity Detectors are made after evaluation and taking into account that of the Fire alarm center transmitted measurement data.
- the fire detectors can be located in different locations and in one of the structure of the the expected fire hazard potential must be arranged in accordance with the alignment, whereby the fire progressively consists of several during the extinguishing process Let us analyze directions.
- Another advantageous embodiment of the invention consists in the additional arrangement a detector element in one or more fire detectors for monitoring the continuous use of extinguishing agent.
- Another advantageous embodiment of the invention is related to the known methods of cyclic extinguishing agent application with controlled Extinguishing agent delivery.
- the sensitivity of the detectors tracks the fire an exact image of the current one corresponding to the current measurement data is created Fire development.
- the parameter settings for the post-erase cycle such as duration and
- the amount of extinguishing agent depends on the degree of danger to the person to be protected Objects.
- Fig. 1 shows the basic structure of a stationary extinguishing system, with a Extinguishing device 1 and a fire alarm device 2, which in particular a variety of fire detectors 4 and their signal lines 13 and their essential elements are arranged in the monitoring area 3.
- the extinguishing device 1 has an extinguishing agent supply that is used in gas extinguishing devices
- the trigger mechanism for the deletion process for example an alarm valve station is via signal lines 13 with a fire alarm device 2 connected.
- the fire detection device 2 can have one or more fire detectors 4 comprise, in turn, one or more detectors 5, 6 of the same or different Type are integrated.
- the detectors 5,6 are preferably optical Radiation detectors designed, the radiation sensitivity in the infrared or ultraviolet wavelength range.
- a fire alarm control center 8 takes over the control for larger stationary extinguishing systems the extinguishing device 1 and the evaluation of the detector signals of the individual Fire detector 4.
- the fire detector 4 is via signal lines 13 connected to the extinguishing device 1 (Fig. 2).
- the amplifier circuits 11, 12 of the detectors 5.6 adapted to the ambient conditions of the fire detector.
- This adjustment can be for example with the help of digital / analog converters, which are controlled by the control unit 7 of the Fire detector 4 can be controlled.
- the fire detector 4 transmits an alarm signal to the extinguishing device 1 and activates the automatic deletion.
- pre-alarm levels in front of the Activation of the automatic extinguishing process or additional fire parameters to be used for fire detection.
- the detectors 5, 6 can expediently be used individually or together in one Fire detectors 4 can be arranged and the same or different fire parameters detect (type A or type B).
- the detectors 5, 6 are activated by means of amplifiers 11, 12 set to a higher sensitivity.
- the extinguishing device 1 continues controlled (triggered) and a preset delete cycle 15 started again (Fig. 3).
- the deletion process can thus consist of a number of deletion cycles 15 and will continue until the fire detector detectors no longer detect fire.
- the fire detectors 4 After detection of the end of the fire, the fire detectors 4 transmit no further Trigger signals to extinguishing device 1 and the deletion process after a preset post-erase time deactivated.
- the preset post-erase time 15 is generated by the control unit 7 Clear stop signal activated.
- the detectors are then returned to normal by means of amplifiers 11, 12 (default) sensitivity reset.
- the fire alarm device 2 in particular its fire alarm 4, can also be used a further suitable detector element 10 for monitoring the use of extinguishing agent be equipped in the event of a fire.
- An extinguishing agent is sufficient if, for example, the extinguishing gas concentration (CO 2 content) in a gas extinguishing device is high enough to suffocate the fire.
- a CO 2 sensor can be used, for example, in a CO 2 extinguishing system or an O 2 sensor in a gas extinguishing system.
- the delete-stop signal of the detector element 10 is dependent on the design of the stationary Extinguishing system either in the control unit 7 of the fire detector 4 or in one Fire alarm center 8 processed and transmitted to the extinguishing device 1.
- the deletion method according to the invention has the particular advantage that the Extinguishing agent is used very specifically and adapted to the course of the fire.
- the continuous or gradual increase in sensitivity of the detectors Fire detector after the first alarm trigger enables a differentiated evaluation of the real fire events.
